-This directory contains mpn functions optimized for MIPS3.  Example of
-processors that implement MIPS3 are R4000, R4400, R4600, R4700, and R8000.

-RELEVANT OPTIMIZATION ISSUES
-
-1. On the R4000 and R4400, branches, both the plain and the "likely" ones,
-   take 3 cycles to execute.  (The fastest possible loop will take 4 cycles,
-   because of the delay insn.)
-
-   On the R4600, branches takes a single cycle
-
-   On the R8000, branches often take no noticable cycles, as they are
-   executed in a separate function unit..
-
-2. The R4000 and R4400 have a load latency of 4 cycles.
-
-3. On the R4000 and R4400, multiplies take a data-dependent number of
-   cycles, contrary to the SGI documentation.  There seem to be 3 or 4
-   possible latencies.
